The Wine Advocate, fully known as Robert Parker's Wine Advocate and informally abbreviated TWA or WA or more recently as RP, is a bimonthly wine publication based in the United States featuring the consumer advice of wine critic Robert M. Parker, Jr.

Initially titled The Baltimore-Washington Wine Advocate the first issue was published in 1978. Accepting no advertising, the newsletter publishes in excess of 12,000 reviews per year, utilizing Parker's rating system that employs a 50–100 point quality scale (Parker Points® or simply RP). These wine ratings have a significant effect on the sales of the reviewed wine.

Robert Parker first developed an interest in wine on a trip to France while in college studying law. In the 1970s, Parker was influenced by the activist consumerism philosophy of Ralph Nader and saw in the wine industry a lack of independent wine criticism that was not sponsored by the distributors or wineries being reviewed. He released his first edition of The Baltimore-Washington Wine Advocate in 1978, originally as a complimentary bi-monthly feature. It soon changed to a subscription periodical and by 1984 was successful enough that Parker could quit practicing law full-time and focus on wine reviews.

Parker and The Wine Advocate first garnered international, mainstream attention for his early prediction of the superiority and quality of the 1982 vintage of Bordeaux wine. Parker's enthusiastic endorsement created a spike of interest from American wine buyers in purchasing wine futures of this vintage, prior to its release to the public. This had the effect of raising the price dramatically for 1982 Bordeaux wines. Subscriptions to The Wine Advocate continued to grow and by 1998 had more than 45,000 subscribers from 35 countries. In 2000, an online version of the magazine was introduced, eRobertParker.com, which expanded the publication beyond Wine Advocate content to include an interactive Bulletin Board managed by Mark Squires and many articles and features not available in the printed version. By 2012, subscribership had grown to about 50,000, with 80% of readers from in the United States.

As of December 2012^[update], many changes were announced concerning the management and format of The Wine Advocate following the sale of a majority stake in the publication to investors from Singapore. A transition from print to fully on-line distribution was announced, to take effect before the end of 2013. The role of editor-in-chief went from Parker to Lisa Perrotti-Brown, a Singapore-based correspondent for the publication. A second editorial office was opened in Singapore.

Following lead critic Antonio Galloni's departure from The Wine Advocate in February 2013, three new critics were recruited adding to what Robert Parker called his "Dream Team". Jeb Dunnuck joined the publication on April 3, 2013, followed by Monica Larner and Luis Gutiérrez on April 23, 2013.

On 22 November 2019 it was announced that Michelin Guide became the sole owner of The Wine Advocate.

Starting in 2001, Parker started to delegate many of the world's wine regions to a team of critics.
